add page.tsx to the folder "pages"

localhost:3000/pages will look for a page.tsx file. If found it renders.

or just rename discordserver.tsx to page.tsx

what's inside page.tsx

the pages folder is supposed to be outside of app folder

and OP's original file naming is correct

look here: https://nextjs.org/docs/pages/building-your-application/routing/pages-and-layouts

why are you using pages dir anyways?

app dir and pages dir are different things, since next 13 it's recommended to use app dir

can i see it?

and rename the pages folder to something else. I think it is a keyword not sure tho

no, default template won't have pages dir inside the app dir

if you want to create a page. the file structure is: app/pagename/page.tsx
